Climate Zone 4
I have an unconditioned basement that I would like to vent to freshen the air. Despite being unconditioned it stays a nice enough temperature, so I had wanted to use a couple LUNOS e2s to not ruin that. However, there isn’t enough above-grade wall to install those (~14″ of block + 2″ sill plate + 7.5″ rim joist).
Any suggestions? I have half mind to install Lunos in an unrecommended manner, but that could be an expensive mistake. Am I crazy to want an ERV/HRV down there? Even if I don’t use heat recovery, using balanced ventilation seems ideal so that I am not (a) bringing conditioned air down into the basement and exhausting it or (b) pushing air into the basement and making it migrate upstairs. Note that the basement door must remain partially open for the cats to get to their litter box (which is one reason why I want ventilation).
